| Popis: |
Nuclei generation and growth in initial photo-polymerization were investigated for a liquid crystal (LC) and light-curable resin mixture. The investigation showed that the dependence of nuclei density on the intensity was divided into three main regions: (1) the nuclei density had threshold exposure at low intensity, (2) the nuclei density was proportional to the intensity at middle intensity, (3) the nuclei density was saturated at high intensity. The nuclei growth also differs according to the initial nuclei density. We found that the nuclei grew large spheres at low nuclei density and the nuclei grew dendrites and eventually a polymer-network is formed at high nuclei density. |
